Bill, when the time comes to replace your old middle or rear A/C you will need to make some choices. The new A/C units are not compatible with the old 5 button thermostat. You can replace both A/C units with new and use a new 10 button thermostat. You can try to find a retrofit control board for your new A/C and use it with your old 5 button thermostat, but these boards have been difficult to find. You could move the front A/C to the back and then pair it with a new A/C and your 10 button thermostat. Then move your remaining old A/C and 5 button thermostat to the front so it is operating by itself. Hope this helps.

Your center A/C has a remote thermostat located either in the bathroom or the kitchen/living room. They are round white plastic vent covers with 2 screws holding it to the wall. Your front A/C was replaced from the original and has the new style Comfort Control thermostat.

You can order the replacement barrel key on eBay and the Trimark key from Trimark. For the ignition, you'll have to remove the key cylinder and take it in, or call an automotive locksmith.

Did you have the fuel filters changed at Speedco? If so, you probably had air in the fuel line after servicing. Hopefully by cycling the key you have removed all the air. It sounds like the start problem uncovered a poor connection or bad solenoid. I would clean all the engine start battery cables, especially the one that attaches to the frame. If that doesn't fix it, then change the solenoid.

Monaco used captain's chairs and furniture from Villa International in the diesel coaches. I was able to contact Villa and order a replacement set. But they were expensive. Do your chairs have the seatbelt built into the chair? If so, it limits your choices. If doing this again I would find a good upholstery shop and have the chairs recovered.

Tires and tire pressures can change fuel mileage by very small amounts (.1 mpg or so), but not by the amount you're seeing. Either the math is wrong or something serious is happening. Hope you figure it out.

The early Aqua Hot units have the freshwater copper loop wrapped around the outside of the boiler tank. They are very vulnerable in freezing conditions, especially the bottom section near the Aqua Hot exhaust exit (see left side of picture). The electric side of your Aqua Hot is very limited. After a few hours it may supply enough hot water to do dishes but not enough for a shower or to heat the inside of the coach. If you can store the coach inside somewhere that would work. I've tried using a small electric heater in the Aqua Hot compartment along with a 100w bulb in the tank dump section. Last year my Aqua Hot developed a leak in the freshwater loop. It may have been from rubbing or possibly from freezing. Your A/C units should have a large foam filter under each unit. You access the filter by lowering the inside decorative cover. Some folks remove the foam to improve airflow as it's only recirculating inside air.

Wow! Beautiful pictures. Thanks for posting.

Yes. In your second picture you see a screw slot stud with a lock nut on it. Center the steering, loosen the lock nut, and turn the screw stud in slightly. Re-lock the nut and test. Monaco used both Sheppard and TRW steering boxes. If you have a Sheppard I'd replace it with a TRW. There is a long thread on IRV2 in the Monaco section. Weller truck parts sells replacement steering boxes just for this application. More detail. The one in the video uses an Allen hex to adjust and most heavy vehicles use a screw slot.

The countertops and most of the showers from Monaco are Dupont Corian. It's fairly easy to work with.

The only issue we had with 50 hertz was our American clocks and timers ran 10 min slow per hour. This was a problem on the washing machine.

Wow that's an interesting combination. When we lived in the UK we had three 2k transformers as well as several small ones. Seemed to work well. I wonder how the UK ended up with 50 hertz.

Monaco purchased the front axle as an assembly. There is a tag on the front axle that will help decode all the parts included. Our front brakes are Bendix ABD22X. Yours may or may not be the same. Bendix ADB22X Disc Brakes (Front).pdf

Both of the Aqua Hot systems we've owned have had soft lines from the enclosure opening to the pump. They are much easier to service than hard line systems.

Set zone 1 to the mode you want by using the Mode button to cycle through Off to Cool or Furnace. Then set the desired temperature. Then switch to zone 2 and set it up similarly. If zone 2 blows hot air when you have Cool selected the unit may be bad. Or, if it's a heat pump model the reversing switch may need replacing.

I've changed several Aladdin tank quantity sensors (pressure transducers). I've also had a new sensor that leaked no matter what I did. Another new sensor wrapped with multiple layers of quality Teflon tape resolved the issue. It's important that you install these hand tight and then wrench tighten only 1/4 turn. After installation then you must go through the Aladdin calibration procedure. (See Aladdin manual) Purchase new sensors here: https://www.nwrvsupply.com/product/aladdin-tank-sensor-16622728/

Wow, that's a beautiful coach. And one of the best model years.

Over on IRV2.com, one or maybe two folks have had issues with the CM870 ISX. But several have had issues with the CM871 650hp engine.

Have you checked the front A/C circuit breaker? It should be in the top circuit breaker box.

I assume you have the 42" Dynasty since you have three A/C units. Do you have a thermostat mid coach that controls the front A/C, and a thermostat in the bedroom that controls the middle and rear A/C units? Or did the installer daisy chain an RJ11 phone cord from the front to the middle A/C and put them all on one thermostat? Do you have any indications at all on the front thermostat? Does your Aqua Hot or furnace operate on the front zone? I would first try a thermostat reset.

I recently replaced our Aqua Hot boiler. On the older 100-01 models, the fresh water copper coil is on the outside of the boiler (see picture). I'd replace the radiator cap and monitor it. Be careful removing the cap. The filler neck is soldered on and can come lose. Good luck!

To clear up some confusion, The Executive, Navigator and 42' Dynasty come with with a 10k 240V Onan generator. The Signature and Marquis come with a 12k 240V Onan generator. Ron, do you have a surge suppressor or EMS after your ATS? I'd be checking and/or replacing it.

Time to replace the entire shock. The Monroes were not very good when new. Look at Bilstein and Koni.

I had pieces of debris in both the regulator and the city water selector. When turning on an inside facet the pressure was good for a few seconds and then reduced to low flow.
